Chinese chipmaker Jiangsu Vertilite Semiconductor Technology is committing US$741 million to build a new research and manufacturing facility in Changzhou focused on indium phosphide (InP) laser chips for AI optical interconnects.
The investment marks Vertilite's expansion beyond its existing VCSEL (vertical-cavity surface-emitting laser) business into high-end components that connect AI data center processors.
What happened
Chinese optical chipmaker Jiangsu Vertilite Semiconductor Technology is investing CNY5 billion (approx. US$741 million) in a new communications chip and device R&D and manufacturing base in Changzhou, moving beyond VCSELs into high-end indium phosphide (InP) laser chips for AI optical interconnects.
Why it matters
AI data centers rely on optical interconnects to move massive amounts of data between processors at high speed; InP laser chips are a key component of that infrastructure. Vertilite's expansion into this segment signals growing competition in the supply chain for AI hardware, particularly from Chinese manufacturers.
What to watch
The facility will be located in Changzhou and serve as both an R&D center and manufacturing base for the new InP laser chip line.

Jiangsu Vertilite Semiconductor Technology's CNY5 billion (approximately US$741 million) investment represents a significant bet on optical interconnect components as AI infrastructure continues to scale. The company is leveraging its existing expertise in optical semiconductors—it currently produces VCSELs, a related laser technology—to enter the higher-margin, more complex InP laser chip market. This vertical expansion reflects the growing importance of optical interconnects in data center architecture, as AI systems demand ever-faster communication between processing nodes. The investment in both R&D and manufacturing capacity in Changzhou suggests Vertilite intends to build domestic supply chain resilience for a component that has historically been dominated by non-Chinese suppliers.
